Alimentäre Thyreotoxikose bei zwei Hunden

Zusammenfassung

Zwei Hunde mit erhöhter Thyroxinkonzentration, von denen einer deutliche klinische Symptome einer Hyperthyreose aufwies, wurden zur diagnostischen Abklärung überwiesen. Mittels gezielter anamnestischer Aufarbeitung, klinischer Untersuchung, weiterführender Labordiagnostik und Szintigraphie konnte eine alimentäre Thyreotoxikose diagnostiziert werden. Ursächlich war in einem Fall die Fütterung von mit Schilddrüsengewebe kontaminiertem rohem Futter (BARF), im anderen Fall ein konventionelles Hundefutter. Nach Futterumstellung verschwanden bei dem betroffenen Hund die klinischen Symptome. Eine Kontrolluntersuchung ergab bei beiden Hunden eine Thyroxinkonzentration im Referenzbereich.

Summary

Two dogs with increased thyroxin concentrations compatible with hyper thyroidism were referred for further examinations. One dog displayed clinical signs of hyperthyroidism. Based on history, clinical examination, laboratory evaluation and scintigraphy an alimentary thyrotoxicosis was identified. It was caused by feeding a BARF diet containing thyroidal tissue in one dog and by conventional dog food in the other patient. After changing the diet the clinical signs resolved in the affected dog. A control examination revealed thyroxin concentrations within the reference range in both dogs.
